Date 2025-04-15 Introduction VNA PCB. Vector network analyzer is a device used to measure scattering parameters of electrical circuits operating at high frequencies. S-parameters tell how much a circuit reflects power back to the source and how much it attenuates or amplifies it to the other ports. Working with S-parameters is an essential part of designing any electronics operating at GHz frequencies. These devices aren't cheap, especially as the operating frequency increases. High end VNAs

Resonate is a low latency, low memory footprint, and low computational cost algorithm to evaluate perceptually relevant spectral information from audio (and other) signals. Overview Resonate builds on a resonator model that accumulates the signal contribution around its resonant frequency in the time domain using the Exponentially Weighted Moving Average (EWMA), also known as a low-pass filter in signal processing. Consistently with on-line perceptual signal analysis, the EWMA gives more weigh

Robert Triggs / Android Authority TL;DR Strings found in MIUI firmware suggest Xiaomi is developing a ‘Chip performance dashboard’ feature. This dashboard would allow users to adjust CPU and GPU frequencies and voltages within safe parameters. Changes would require a reboot and will undergo system checks to ensure that the phone works well enough. Most Android flagships these days come with overkill processors, and frankly, most of us don’t need that much processing power for our everyday ta

Pi Pico Rx - A crystal radio for the digital age?¶ My first step into the world of electronics was with a crystal radio, just like this one. Back then, I don’t think it has ever occurred to me that I could make a radio myself, so I wasn’t expecting it to work. But when I put the earphone in, I was amazed to hear very faint sounds coming through. I couldn’t believe that building a radio could be so simple, and the best part was, it didn’t need any batteries! That little experience sparked my in

Use triple buffering if and when the previous frame is running late. This means the next frame will be dispatched on time instead of also starting late. It also triggers a GPU clock boost if deemed necessary by the driver. Although frequency scaling is not required to get a performance gain here because even a fixed frequency GPU will benefit from not over-sleeping since CPU/GPU parallelism is improved. If the previous frame is not running late then we stick to double buffering so there's no la

Principle of STCM-based communication and sensing Referring to the concept illustrated in Fig. 1, the proposed scheme features an STCM that manipulates the incoming EM wave, controlling the direction of propagation of the fundamental frequency and simultaneously generating spatially distributed harmonics. The fundamental-frequency wave is used for communication, while the spatial-spectral characteristics of the harmonics are processed to accurately estimate the direction of arrival (DOA) of som
